PROTECTING DEVICE FR SPRNGS.

Application filed May 14, 1925.

aruuission and adherence of dust or dirt to the extra-lor or interior sui-tace ot the spring.

'lhe primary object ot my invention is` to provide a casing or closure shaped to ,contorni with a spring, constructed and arranged so as to prevent the admission ot dust or dirt thereto yet permit of the expansion and contraction ol the spring when so encased.

Another object ot my invention is to provide a casing or closure for a coiled or helical spring consisting of two or more sections movable relatively to each other when the spring is contracted or expanded without exerting any pressure or strain on the closure or protecting device.

A. continued object ot' my invention is to provide a dust preventative device for coiled springs being particularly designed tor coiled springs used in connection with bed springs so that a sanitary construction may be produced.

in order to more fully understand and appreciate my invention, reference is had to the accompanying drawings, showing one ot its many applications to springs in general and particularly bed springs.

Figure l is an enlarged, fragmentary View showing the protecting devices. y

Figure 2 is a sectional view taken substantially en the line 2*?, ot Figure 1.

Figure 3 is a modified form of the invention, one end being shown partly in section.

Figure 4 is a further modified form, one end thereot' being shown partly in section,

Referring new to the drawings, wherein lil'te reference characters designate corresponding parts throughout the several views, :3 designates the end trame ot a bed spring and (i, 7, the open links and hooked links, usually connected to the ends 5 of the frame by coiled spring 8 as clearly shown by Figure 2 ot the drawings. The ends 9, 10, of the coiled spring 8 are usually extended to receive the hooks 11, whereby they may be attached to the frame 5 as well as to the links 6, 7, above referred to. Under ordinary conditions dust and dirt from the room accumulate on the interior and ex terior surface of the springs 8 and it is Serial No. 30.137.

very difficult to lreep the interior o'l the springs tree from dust and dirt unless a special spring cleaning element is used, which can enter the surfaces ot the spring proper. By reason of the great number oit coiled springs that enter in the production ot a standard bed spring, it will be readily recognized that the cleaning ot the coils is usually a very tedious one.

In order to overcome the above diiiiculty, a protective device in the form of a closure or casing, which, as clearly shown by Figure 2, showing the preferred embodiment ot my invention, is provided and consists of a sectional shell, shaped to conterm with the coiled spring 8, above referred to. rlhe sectionsA 12, 13, interiit so as to be slidable relatively to each other. @ne end of each of the sections 12, 13, is open and the opposite ends 14, 15, of the respective sections are closed and extended so as to engage and grip the ends 9, 10, ot the coiled spring 8, which is encased. rThe ends 14, 15, of the respective sections ot the casing or closure are provided with apertures lor,` the passage of the hooks and the hooks or loops of the links 6, 7, of the spring proper. In this manner it will be seen that regardless oit the stress and strain exerted on the coiled springs 8, the protective casing or closure will remain intact relatively to each other and thus no pressure would be directly exerted on the respective sections 12, 13, tending to separate them from the coiled spring. The coiled spring, therefore, is entirely encased, prevents the admission of dust or dirt thereto, and produces a more sanitary bed spring when the protective casing is no utilized.

In Figure 3, I have also shown a protective casing consisting of the interlitting or telescopic sections 16, 17, tor enclosing a coiled spring 18. in aperture 19 :is formed at each end et the sections 16, 17, whereby the ends of the Wire ot the spring 18 may be passed and bent in the form ot a hook 2O so as to be fastened to the iframe and to the links of the bed spring.

In Figure 4, the second modification ot my invention consists of a central sleeve 21 having end caps or heads 22, 23, which are slidable relative to the sleeve 21, said caps being also provided with apertures for the passage of the. ends of the wire constituting the coiled spring so that the said ends of lili) theV Wire may be bent in the 'form of a hook and attached to the said bed spring Jframe and the links.

While I have shown my invention as applied to and used in connection With a coiled spring for a bed spring, it will be readily recognized that the invention is equally applicable in other instances Where it is desired to protect a spring from dust and dirt accumulations. ln actual practice, the protective casing may be constructed of diilerent kinds of material and I do not wish to be limited or restricted to the shape ot the protective casing or the material trom Which it is made, since this may be obviously mcdi fied as n'ianufacturing` necessities may require.

Having thus shown and described my invention, What claim as new and desire to secure by United States Letters Patent is l. A protective device ter springs comprising a casing having tivo telescopic sections1 each ot said sections being open at its inner' end and closed at its outer end, the outer ends being extended and having an aperture therethrough and fastening means passing through said apertures whereby the ends of the encased spring may be attached. 2. A protective device for springs come prising a casing having tivo telescopic sections, relatively movable, each of said sections being open at its inner end and closed at its outer end, the outer ends being eX- tended and flattened to receive the. ends of the encased spring, said outer ends having apertures therethrough and hooks connected to said apertures whereby the encased spring may be attached. in. A device of the class described comprising a casing having two telescopic sections,

each of said sections being open at its inner Y ,end and closed at its outer end` a coiled spring Within said sections, the ends of said spring engaging the closed ends of said telescopic sections and hooks connecting the ends of the coiled spring whereby the telescopic secticns may be moved relatively to cach other upon expansion and contraction ot said spring.

In testimony whereof I atiix my signature.
